BALlNG- SPECIFICATION forming part of Letters Application filed February 9, 1891.

ToaZZ whom, ift may concern:

Be it known that I, JOSEPH R. JOHNSON, of Indianapolis, county of Marion, and State of Indiana, have inventedcertain new and useful Improvements in Ealing-Presses; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like letters refer to like parts.

My invention `relates to improvements in the construction of machines for pressing hay and other fibrous or loose material, wherein a rebounding plunger is used 5 and it consists in the peculiar mechanism for operating the plun ger and releasingr it at the proper moment, allowing its rebound or retraction, and willbe understood from the following description.

In the drawings, Figure l is a side elevation of one end of the press, showing the operating parts of my device. Fig. 2 is a top view of the same. Fig. 3 is al section of Fig. 2 on the line a; Fig. 4 is a det-ached sectional view across the diameter of the large gear-wheels that operate the plunger on the line of the crank-wrist. Fig. 5 is a face view of one of the cranks.

In detail l is the frame-work having boxings 2, upon which is mounted the shaft 3 of the driving-pulley 4 and the fly-wheel 5.

6 is a small gear-wheel or pinion mounted on the opposite end of this shaft, engaging with a large gear-wheel 7, mounted on the counter-shaft 8, this counter-shaft also carrying pinions 9, which engage with gearwheels 10, which preferably have rounded teeth and are loosely mounted on short axles 11, carried in boxings l2,sustained bybraces 13, bolted to the sides'of the frame.

1G are cranks keyed on the inner ends of the axles 11, provided with lugs or proj ections 17 on their lower ends for bearing lightly against the inner face of the gearovheels lO and preventing any twisting movement.

18 is a wrist which passes through openings 19 in the lower end of the cranks, and 2O isa plunger-bar attached directly to the central part of this wrist, the ends of the wrist resting against the inner periphery of the gearwheels whose spokes are outwardly curved at their outer ends to allow the free passage P R E S S..

of the wrist as the wheels rotate. One of these spokes, however, is straight, and is preferably notched, as at 22, the spoke being thickened at that point for greater strength,

'and as the gear-wheels revolve these notches 55 will engagewith the ends of the crank-wrist 1S, as shown in Fig. l, where the latter is shown as about to be released from the notch of the spoke.

The gear-wheel lO is provided with an extension 23 of the hub on the outer side, this extension forming a sleeve or hollow spindle which is journaled in a post-boxing 24, formed integral with plates 25, which have holes through which the device is bolted to the frame-work, as shown in Fig. l. The weight of the wheel, therefore, is carried in this postboxing, so that the short axle Il has a free movement of its own while the mechanism is revolving, the outer boxing l2, which provides a bearing for the end of the shaft 1l, being added for greater security.

Power being applied to my machine,the operation-is as follows: The pulley 4 on the shaft 3, with its pinion G revolving, in turn revolves the gear-wheel 7, and the shaft S that carries the pinions 9, which in turn revolves the large gear-wheels lO, these latter revolving in the direction indicated by arrows in Fig. 1 until the notches 22 in the spokes 2l engage with the outer ends ofthe crank-wrist 1S, connected with the plunger, carrying the wrist and its parts around with the gearwheels until the crank-wrist 18 is carried below the line of attachment of the plunger-rod to the plunger, when the wrist will slip out of the notches 22, and the pitman, if the material be elastic, will rebound and be thrown back in the position shown in Fig. 3, and further stopped until the notches of the spokes 21 as they are carried around will again en gage with the wrist. If the material being pressed be wet or inelastic from any cause, the plunger' will not rebound,but will yet be released from the driving gear-wheels in the manner above described, and as these wheels continue their movement they will carry back the pitman and again carry it over with the cranks and effect the forward stroke as before. As the plunger rebounds its upper surroo face comes in frictionnl contact with the arms of a brake (not, shown) which is conirollci'l hg' a coiled spring 223, (shown in liig. 1;) bul, as this is no partof my invention it need notI be further described.

That I claim as my invention, and desire to secure by Letters Patent, is the following:

l. In a hailing-press, a frame-work, a plun- `ger movable therein, a pitman connected to such plunger at one end and at the opposite end to a crank-wrist connected by cranks to short axles having bearings in suitable boxings, geaihwheels mounted on the short axles having,` hub-extensions sustained in independent boxings secured to the frame-work, one of the spokes of such gear-wheels adapted to engage with the crank-wrist, carrying the same over with the wheel, whereby the forward movement of the pitnian is effected and the release of such pitinan by the further movement of t-he wheel,allowingthe rebound of the plunger, substantially as shown and described.

2. In a baiing-press, a frame-work, a plunger movable therein, a pitmanconnected at one end to such plunger, its opposite end connected to a crank-wrist carried hy cranks connected to short axles sustained in suitable boxings, a pair ot gear-wheels actuated from the main driving-shaft and having hub-ex tensions independently journaled in post-boxings connected to the frame-work, the axles ot' the cranks also journaled in the hubs of the g'earwwheels, the latter having curved spokes to admit the passage of the ends of the crank-wrist which projects inside the face o1 the gear\vl1eels, a single spoke of each gear-wheel beingre-enforced and notched for engaging; with the crank-wrist, whereby the cranks and gear-wheels are revolved together, effecting the forward movement of the plunger, and means` substantially as described, for releasing the crank-wrist from engagement with the wheel and providing for its backward movement.

In witness whereof I have hereunto set; my hand this 4th day of February, 1891.

JOSEPH R.. JOHNSON.
